Q I've read that early treatment of autism can make a big difference. But what are the early signs of autism?
A You're right -- my colleagues who are experts in autism say that early recognition and treatment really can help.
Autism (also called autism spectrum disorder, or ASD) is a developmental disorder of the brain. Kids and adults with autism have problems communicating and interacting socially.
They also may have unusual behavior patterns, interests and activities. Symptoms range from mild to severe. Autism symptoms are usually apparent by the time a child is 2 or 3 years old.
What should you look out for? Children with autism may not show signs of it during their first year. Those who do may not hit typical developmental milestones on schedule.
For example, they may not smile at the sound of their mother's voice, point out objects to catch someone's attention or maintain eye contact. And they may respond negatively to being touched or cuddled.
Behaviors become more apparent in toddlers and young children. For example:
- Disordered play. A toddler with autism usually prefers to play alone and is unlikely to engage in make-believe play. He or she may spend hours repeatedly laying out objects in lines or concentrating on one object or topic. Any attempt to divert the child can provoke an emotional outburst.
